Abstract Scope |
The stochastic formation of defects during Laser Powder Bed Fusion (L-PBF) negatively impacts its adoption for high-precision use cases. Optical monitoring techniques can be used to identify defects based on layer-wise imaging, but these methods can be difficult to scale to high resolutions due to cost and memory constraints. Therefore, we implement generative deep learning models to link low-cost, low-resolution images of the build plate to detailed high-resolution images of the build plate, enabling cost-efficient process monitoring. To do so, a conditional probabilistic diffusion model is trained to produce realistic high-resolution images of the build plate from low-resolution webcam images, recovering the distribution of small-scale features and surface roughness. We evaluate the performance of the model by analyzing the statistical properties of the generated images, in addition to the similarity between the image anomalies detected by the high-resolution model to the generated samples. |
